Proud to share our first lab pre-print: “SND3 is the membrane insertase within a fungal multipass translocon” where @tzujingyang.bsky.social solved the structure of a ribosome-associated SND3-translocon complex involved in ER membrane protein insertion ➡️ doi.org/10.1101/2025...

Our paper on prediction of phase-separation propensities of disordered proteins from sequence is now published:
www.pnas.org/doi/10.1073/...

The paper has been substantially updated compared to the preprint including new experimental data and using the neural network to finetune CALVADOS. 1/n

✨✨ It's #glycotime for #HIV Env ✨✨

N-linked glycans modulate flexibility & MPER epitope exposure #glycotime

Huge effort by @shehata92.bsky.social @lcasalino88.bsky.social with cryoET of Env in VLPs by @thevillalab.bsky.social & team 💪

Would love feedback!

Thrilled to share these experiments on shaping focused ion beams to explore different ways of milling. Here, we explore using different beam geometries to generate cellular thin sections/lamellae. The video shows elongating the beam on a charging spot burn www.biorxiv.org/content/10.1...

Excited to see work led by @autophazeke.bsky.social, @minghaochen.bsky.social, Thanh Nguyen, and Ainara Claveras out in @science.org today, the culmination of a 15-year project to understand structurally how the synthesis of the critical lipid of autophagy, PI3P, is regulated. tinyurl.com/ywvjh8u4
